Speedometer Off Calibration 'Fixed'
I bought this 2013 pickup used a few months ago. It was originally sold in Canada as the FXR.The speedometer was off by 4 MPH. I was going slower than the meter reading. Just recently I took notice that the speedometer was off even when the engine was off.

I started searching the net for a fix and all I could find was, "live with it" or "go to dealership for a replacement speedometer". Hmmm! I also learned that when the Canadian trucks are sold at auction they are prepped for US import. Part of that prepping involves replacing the dash instrument cluster overlay. Canadian overlays have kilometers on the outer speedometer ring of numbers whereas US overlays have miles on the outer ring. So, if someone is replacing the overlay, I should be able to fix the speedometer guessing that's when it got off calibration from the factory.

Lower steering wheel, remove 2 screws (orange arrows) 7mm hex head, gently pull trim ring starting at the top, work way down the sides. Clips will release. There is a thin notch under the dash top. Insure the trim ring lip aligns into the notch upon reassembly.

Remove two black screws at the top (7mm) and two at the bottom of the instrument cluster. Excuse the dust. That's what happens when you get a load of mulch and leave the window open. Ugh! Remove the electrical connector at the top right corner of the cluster. There is a release tab for the connector center backside. Remove the cluster from the dash.

To remove the clear plastic, first remove the two silver screws (T15 Torx). These two screws will cause white particles of plastic to get between the clear plastic and the gauges. We'll clean it later.

The black and clear plastic are bonded together. No need to separate the clear and black plastic. Access to the needle at this point requires removing the black plastic section. There are 8 black clips that need to be released. Gently pry them back with your finger nails or screwdriver. The bottom middle clip required a right angle pick. I'm wearing nitrile gloves to keep finger oils off the visible cluster surfaces.

Once the clear lens is out of the way, grip the needle center with finger tips. Roll finger tips toward palm to pry the needle off. Keep in mind to not bend the metal shaft the needle turns on.

Needle and needle shaft are round and not keyed. Hover needle above the shaft in the desired orientation, then lightly press it on the shaft. If pressed on too far the needle will drag on the overlay. The force required to pull it off is much greater than the force to put it on.

Clean dust with compressed air 5-10 PSI and a small clean dry artist brush. My center display screen had a splattering of 3D spots (dried sneeze drool or sticky soda) from the import preppers I presume. I cleaned it with several cotton ***** lightly soaked with IPA (rubbing alcohol). It left a haze until cleaned then I had to brush away the fibers. If you use any other chemicals, be aware some will discolor or melt plastic ruining the display. Test the gauge by plugging it in. If it's not aligned, pull the needle off and try again. If the cluster is disconnected for more than 90 seconds, plugging it in will cause the needles to self test and center on calibrated zero (key is off and out of the ignition when it does this). When satisfied with the needle placement and cleanliness, clip the clear lens back on and reinstall all the screws in reverse order.
I test drove the pickup and compared my pickup speedometer to a phone app. It was dead on. I know about the Engineering mode digital speedometer but I normally don't drive with it on and I used the phone app prior to adjusting the speedometer needle. I also used my wife's car driving with her adaptive cruise control on to compare my speed with her speed and phone app. Me so happy now!

Great write up. My speedo reads 5mph low (the PCM knows the correct speed as verified by Forscan and my HUD, the speedo is just low), so I was going to try this once it stops being hot. It’s nice to see that it’s doable without having to use a hot knife on the plastic.
Thanks!
Thanks!
I would agree that this is the fix if the speedo is a fixed amount out (say 5 mph at all speeds). If the difference is more of a percentage (say 1.5mph at 30, 2.5mph at 50 and 3.5mph at 70) it is likely the calibration in the PCM/BCM.
I recently started having this issue, speedo on at low speeds and progressively more off the higher the speed. It was only about 5mph off at 60 but recently got worse and is now 10mph faster than the speedo says at 25-30 mph. Is there a way to reset the PCM/bcm?
First off, the calibration in the PCM/BCM doesn't just change itself. Have you changed tire size, gear ratio or had any computer updates?
Sometimes you can correct this issue with the speedo reading a low or high by putting the cluster into engineering test mode. The gauges will flutter and then sweep to full and back to their resting point. But this only works with higher trim cluster that has the 4.2" screen
